What is the minimum age required to drive in interstate commerce?

The minimum age required to drive in interstate commerce is 21 years because federal regulations set by the Federal Motor Carrier Safety Administration (FMCSA) establish this age limit for commercial drivers. This requirement is designed to ensure that drivers have the necessary maturity and experience to operate large vehicles safely across state lines. Drivers at this age are typically expected to have more life experience and better judgment in handling the responsibilities associated with driving commercially. Additionally, this age restriction also aligns with other regulations concerning the transportation of goods and passengers, particularly concerning safety standards in interstate operations.
